Show expanded CRS arguments
Wrappers for sp::CRS and inla.CRS objects to handle the
coordinate reference system argument string.
These methods should no longer be used with PROJ6/rgdal3;
see fm_crs_get_wkt() for a new approach.
fm_CRS_as_list(x, ...) fm_list_as_CRS(x, ...) fm_CRSargs(x, ...) fm_list_as_CRSargs(x, ...) fm_CRSargs_as_list(x, ...)

Additional arguments passed on to other methods. |
For fm_CRSargs and fm_list_as_CRSargs, a character
string with PROJ.4 arguments.
For fm_CRS_as_list and fm_CRSargs_as_list, a list of
name/value pairs.
For fm_list_as_CRS, a CRS or inla.CRS object.
For fm_list_as_CRSargs(), a CRS proj4 string for name=value pair list
For fm_CRSargs_as_list(), a list of name=value pairs from CRS proj4 string
